Just got back from 3 days at Burro Creek Campground, AZ. It's located 50 north of Wickenburg, AZ off of Hwy 93. Rustic BLM campground with water for filling tanks, flush toilets and a dump station on site. Most of the spots are pretty level dirt spurs with fire rings and tables (under a cover). The sites are $10 bucks anight and some spots are large enough for two(same price as one according to the host).
Burro Creek runs by the campground and its a favorite spot for rockhounds. There was a group of rockhounds there for the week-end. It also appears to be a favorite spot for quailhunters. We met about 6-8 hunters with their dogs there hunting. Most from Idaho and I was pleasently surprised to see about 8 Nash trailers at the campground.
I'd give it an 8 out of 10. It's kinda remote, but a nice get-away.
